Senior Java Developer in healthcareplanning for a client located inthe Netherlands.I optimized the performance of the staff planning tool for this client as 140.000 active users from 180 companies access the application each month to check their schedule both on desktop browsers and mobile devices on this tool.

  - create new templates for emails and notifications
  - update existing processes and java classes calling Camunda BPMN, according to new
  specifications
  - find the cause of performance production issues and do the fixing
• I ensured the app migration from Java 8to Java 11and to Groovy LTS, a key upgrade for the app performance.Some key figures of this project: upgrades for 50 mavendependencies, 14 maven plugins, the oldest being released back in 2011, with a medium plugin age of 4 years.

Senior Analyst Programmer, SC Selir SRL Galati

April 1998 - Dec. 2016

• Development andmaintenanceof banking applications for the mother company based in Italy, Banca Sella Group.
• Platforms I had used on this position in the company: Java EE,Ejb, Servlets,Jdbc,Web-services Jax-ws, Oracle,PL/SQL, Xml, Jaxb, JavaScript, Html, Svn, Maven, Ant, Junit, Microsoft Asp+Oracle, Java+SQL Server, Jsp, Tomcat, Linux/Unix
• The first project correlated with a strategic moment for the Banca Sella Group. Back then, most of the IT used to be managed on the mainframe. For the change of year in 2000, the bank migrated all Cobol mainframe programs. The more technical solution for doing this change, using free and open source software and not the mainframe, was proposed by me within the company and was accepted. This migration took 18 months in total, and I’ve lead the team of 10 members for this project.
  The president of the Group’s Board of Management personally saluted our team for the results as the project was completed successfully 18 months after the project was approved by the Group, with no errors at all.
